Trigger Problem if discovery of new host is new

[MJC3125]

hello all,

I am new to Zabbix, have been given control after the last person left the business.

I need Zabbix to Trigger a problem and email when a new host is found in discovery when this new host is not listed in Configuration>Hosts.

Ie. ICMP PING 192.168.0.2 is found in Discovery but is not listed in Configuration>Hosts for monitoring.

Can this be done?

Yes, try looking at Actions: https://www.zabbix.com/documentation...cations/action

There's a specific set of actions for Discovery Rules, explore that.

When I Look in Configuration > Actions, in the drop-down list is nothing about Discovery Rules in Conditions

Did you get an answer to your question? I had Discovery and Discovery Actions set up previously, working fine. After upgrading to 5.0 I can't find any Action in relation to Discovery - all about alerting and messaging it seems...

Check this out that I just found on another thread...

No I am no closer to getting my problem fixed, can not work out the conditions

I think I have a working solution.
Basically setting up a template with an item that reads the inventory install date from the host, and a trigger that fires if install date is not set.
When a new device is discovered, a discovery action creates a new host, and links a template. A template Item reads the installed date inventory field from the host, and trigger reports a problem, resolved once an install date is manually added to host.
I'm using Zabbix 7.2

Go to Data Collection > Templates
Create a new template (I just added it to the "Templates" template group)


Add item, the parameter is as follows,

name: install value: {INVENTORY.HW.DATE.INSTALL}

The script is:

return JSON.parse(value).install;

Add Trigger, expression:

last(/New Device Alerting/installdate)="*UNKNOWN*"
or
last(/New Device Alerting/installdate)=""

Go to Alerts > Actions > Discovery Actions
Create or update your rule, to link your new template to discovered hosts.


If you have existing hosts you don't want to trigger problems, you can do a mass update through Data collection > Hosts
Select known hosts, and click "Mass update" at the bottom.
In the inventory tab, check "Inventory Mode" and select "Manual". Check "Date HW installed" and fill in a non-empty value
